The Door is a 1968 WB-7A cartoon. Much like "Norman Normal" which was released the same year, it is neither part of the Looney Tunes or Merrie Melodies series (though unlike "Norman Normal" it was not released as a "Cartoon Special" either). It is an independent short that was not produced by Warner Bros. Animation, but instead produced by the Silver-Campbell-Cosby Corporation and directed by Ken Mundie.
Two stylized, watercolor-rendered American Indians go hunting, to the scat-sung, mumbled jazz soundtrack. They come upon an Indian maiden who shows them a strange door. They open the door and see live-action shots of busy cities, war, and other modern chaos. As they see this, the music becomes more and more frantic. The ending of the cartoon shows an atomic bomb exploding as the door closes, revealing the precautionary, and very 1960s message: "peace."
- Blu-Ray - Looney Tunes Platinum Collection: Volume 1, Disc 3. It is restored and remastered. Prior to that, it was never released on home video.
- This used to be considered by many to be one of the rarest cartoons Warner Bros. has ever made, due to the fact that it wasn't designed to interest children. It is even rare in availability on internet streamings.
